Definitions

the purpose of the present invention is therefore to provide a method and a device which allow the attacking bleeding moment to be divided into a tensile and a compressive component, the point of application being as possible comes to lie near the neutral zone in the profile to be bent.
an apparatus having at least three rollers in which the middle roller is connected by means of an angle bracket rigidly attached to the adjustable slide and a console mounted thereon for receiving profile-specific guide elements.
the rolling unit shown in Fig. 1 consists of the two outer rollers 1, 2 and the middle roller 3. Both the distance of the two rollers 1 and 2 from each other and the distance of the axis 6 or roller 3 from the axes 4, 5 of the rollers 1, 2 connecting straight lines are adjustable bar. If a workpiece 7 is now introduced in the direction X into the opening between a profile-specific guide element 10 and support disks of the roller 3, respectively. pushed between the support disks of rollers 1, 2 and then moved in the direction of arrows X, its radius of curvature is reduced. If this operation is repeated several times, the roller 3 being displaced in the direction of the arrow Y after each passage of the workpiece 7, the radius of curvature is further reduced.
FIG. 2 illustrates the device with the angle bracket 8, which is fixedly connected to the carriage on which the deliverable roller 3 sits and the rigid bracket 9, which serves as a carrier for the profile-specific guide element. 10 serves.
the workpiece 7 is guided between the guide element 10 and support disks of the roller 3, the guide element 10 being able to be prestressed in the Y direction by means of locking screws in slots 11 with the feed screw 12.
FIG 3 shows a sectional view of the device with a different type of workpiece 13. Without the profile specific guide element 14 would pull the wall on the outside of the arch towards the inside during bending.
the shape and material of the guide elements be adapted to the respective profile shapes and materials.
the method and the device for its execution allow workpieces of relatively large width or rather high free-standing walls, respectively. with free-standing formations, to bend into arches or rings and to carry out the bending process continuously.
the device can at any suitable bending, respectively.
Rolling machine can be attached.
